'tvhich enters an extension 13*fformed on the upper end of the 1mixing" chamber, the di"-'. *ameter' of said extension' being siich'as" to A 2 fchemica l "containerjdhas been entered-i in rmixing' chamber 1,; a cap" 14" Is screwedintoj' t a t on r lidm tfl ter; such? as calc um carbi-deiis" entered in:

the chemicahc'ontainer and liquid i'sithen I discharged into the open end of the-p ably consisting of water, and in order to prevent heat, common in gases ofthis nature, a due mixture of a liquid chemical is added to the Water, preferably consisting of denatured alcohol. Thisis according to a process disclosed and claimed in my copending application, Serial No. 280,392, filed March 3, 1919. The water/and alcohol are fed by gravity into the container through a pipe 15 which extends a distance above the mixing chamber 1,-a nd. isprovided at its upper end with elbows 16 and 17,to which areattachedtanks 18 and 19 for the recep tion of water and the alcohol respectively. The control valves 20 and 21 are inserted in the elbows 16 and 17 respectively for controlling the passage of the liquid from the tanks'18 and 19, and likewise a valve 22 is placed in the pipe 15 sothat all the liquid maybe shut off from the container when desired. As more or less pressure results in the tanks 18 and 19, the liquids are introduced into saidtanks through valves 23 and 24 respectively at the upper ends thereof..

The inner end of the pipe 15 terminates in a nozzle 25, the free end of which is nor mally positioned over the container 6, but may be slightly rotated in its joint at the valve 22, so "as to cause the liquid to dis-v charge atone side of the container .6, directly into the mixing chamber 1 for a purpose to be here nafter set forth.

If for any reasonthe proper mixture from the tanks. 18 and 19 should fail, that is to say,jshould a less amount of the alcohol be discharged on to the container than the prescribed quantity, overheating would result, and to provide against such an emergency, automatically operated means is utilized for. supplying the proper amount of the alcohol.

Tothis end, a heat influenced thermometer gauge and electric switch 26is attached to the mixing chamber 1, and this gaugeis electrically connected to a-inotor 27, wh1cli has facrank 28 thereon adapted to be swung in the arc ofa. circle by the operationof the motor. "The crank 28 is inturn attached to a cable-29f which passes oversheaves3O and isattached to a lever 31 of a valve 32, said valve being interposed to a feed pipe 33, one end of which enters the mixing chain ber 1 and the opposite end a tank 34, in which is stored a quantity of alcohol. The

upper end of this tank is also closed with a valve 35 so as tomake the same air tight. The inner end of the pipe 33 terminates in a nozzle36 which is-likewise positioned. over one edge of the container 6, as best shown in Fig. 2. The container is removed from the mixing chamberbyelevating therod 5 until the disk 12 passes above the; edge of the extension 13, when the'rod 5'may be container 6 readily passing by the ends of the nozzles.

The gas formed by the carbide passes from the mixing chamber into a storage tank 37, which may be of any preferred size, the mixing' chamberand tank being connected by a pipe 38 in which is placed a valve 39 for controlling the discharge of gas from the mixing chamber to the tank. The lower wall 40 of the tank is preferably concave so that any sediment in the gas will move by gravity. tothe axial center of the bottom wall and may be discharged therefrom through a stop cook 41. The gas passes from the storage tank 37 through the'pipe line 42 to any suitablepoint. An escape pipe 43 is attached to the upper portion of the tank 37 which has a valve 44 at a point. above the tank, and when the valvewhe-el 45 is operated to open the valve 44 the gas will escape from the tank and pass into the atmosphere.

As a further precautionary measure against explosion, an auxiliary escape jpipe 46 is extended from the top portion of the tank andis connected to the escape pipe 43 at a point above the valve 44, said auxiliary pipe having a pop valve structure 47 controlled pipe, but under unusual pressure the pop I valve will be, automatically opened and re the storage tank.

As a matter of safety the valve wheel 45 hasears 49 extending from opposite sides thereof 5 (F ig, 3) to which are attached chains 50, and saidchains are preferably lease the gas, thus reducing the pressure in extended to a point where the valve may be operated from the exterior of the building, 1

so that should the building catch fire and it would be impossible to gain access to the tank from the interiorv of, the building, the valve maybe operated to release the gas from the exterior of the building, thus preventingan explosion.

f In operatin the device accordin tom previouslyv mentioned process, the tank 18 is filled with water and the tanks 19 and 34 with liquid chemical the valves 20, 21 and 32 being closed. The chemical container 6 is also removed from the mixing chamber 1 and filled with calcium carbide, after which the container is returned into the mixingcham-berand the cap 14 screwed'into the end of the extension 13. The valves 20 and 21, and the valve 22 are then opened, and valves 20 .and 21 then adjusted to permit the escape of the proper amount of water and alcohol from their respective tanks to produce the proper mixture to'be discharged into thempper end of the container 6.

, alcohol When the mixture strikes thecontents of the container the carbide and Water react, the 1 preventing violent reaction] of the I I regulating theflowof Water and liquid" carbide. V

Should for any reason-the chemical in tank 19 fail to maintain the gas in a cooled state as it is 'formed, and-likewise prevent heating of thelsediment in the bottom of-Lthe mixing-chamber1,.so thatconsiderableztemperature will be formed in the.-mi'xing1cham- .7 ber the motor 27 will beenergized and the valve 32 opened, thereby admittingthe liq- =uid from the tank 37, and said liquid may be admitted in such quantitiesas to entirely stop the formation of gas from thecarbid'e. Solong as no water comes in *contactwwith the "carbide remaining in the container, such "carbide will be preserved .nntil water is again discharged'thereon. we r r The container 6 is of ssuchdimensions Tfi'S to produce :a sufiicient amount of gas tofill the tank to its'capa'eitm'andthe amount-of I the gas may be formed rapidly or slowly as I full amount of gas Will be rapidlya'formedi desired. That is tosay, whenithe com taineris "positioned as shown in Fig: 1' :of the drawings, andthe avaterxand alcohol is turned" onto their full mixing capacity, the

. but vbyilowering the container'on therod '5 and then turning the end-of thefnozzle '25 until the contents is discharged directly-into the mixing chamber Without coming in direct contact with the chemical container, the

- gas willbe slowly formed as'the Waterarises chamber 1 and the operator should openthe valve 22 and forget to open the valve :39, the pressure in the mixing chamber l, would certain degree.

in the mixing chamber,- and as the contents of the container will form but a'single, tank of the gas, it is not necessary to pay particular attention to the apparatus during this operation.

In recharging the container 6 it is necessary to close both the valves 22 and 39, and should a recharge be entered in the mixing become so great that an explosion might occur, and to guard against such an emergency a pipe51 is extended from the mixing chamher 1 to the escapepipe, 43 and is connected 7 to the escape pipe above the valve a l. In the pipe 51 is provided an automatically operated valve 52 which will remain closed under ordinary pressure but will automatically open When thepressure arises above-a a chemical tank, means for conveying Water and liquid chemical together from said tanks and discharging their mixture on to the In addition to the escape chemical in thecontainertfor'expanding and forming a gas from the chemical in the container, and means 'for independently chemicals.
